nic

Hello all, I recently bought a Mellanox ConnectX-4 EN MCX415A-BCAT NIC card, and installed it into my Proxmox machine. I can see it among the network devices, I can query it`s speed and it displays the expected value, which is 40Gbits. So everything looks, and works as I expect, but then I...

I was unable to see any of the 4 ethernet ports I have (eno1-4) using `ip link show` after upgrading to Proxmox 8. When choosing to boot from the earlier kernel, it immediately shows up. Is my NIC no longer supported? Included in this category because it is a kernel-level issue. Thank y'all...

I'm trying to figure out the best way to ensure corosync has its own network. Please let me know if any of these points weren't ideal and why: I created a VLAN with no gateway (just a space on my switch with a unique subnet) 10.5.0.X and set all 8x of my nodes to addresses on that subnet. I...

Hi guys! I need some help with a 10G NIC. A client was running a new server and the 10G appears on the web interface, but in the console not. How can i try to "install" this NIC in this server?

I have an 12 node homelab that is regularly losing quorum. I think it might be due to a combination of high bandwidth activities (e.g. backups to a separate PBS server) and corosync being latency sensitive. The 12 nodes are almost all 1L PCs (e.g. Dell and Lenovo tiny/micro form factors). I...
